Does running 18" + wheels on a Yukon/Tahoe sized vehicle radically effect its towing safety? Towing as in a Chevelle on a steel trailer that is? THNX!

I stopped by the local 'bling' store awhile ago to look at new rims for my truck. They would be 22" with low-profile tires. That was my first question was about the payload and towing capacity. The guy told me that it wouldn't affect it and he has had customers with Hummers and 26" rims towing boats.

But coming from who that was, I don't know whether to trust it or not. But, thats what I have been told.

It will affect you on rough surfaces, you can count on it. Smooth surfaced are not any trouble. Saw a wheel on Suburban hit a small pot hole and broke the rim with trailer/car being towed behind. Stopped to help and found out he had broken 2 wheels previously. Not enough tire to cushion the rim from rough pavement.

Most wheels that are DOT approved will have a max weight rating just as tires do. All tires have a max weight rating or load that it can safely carry.

Gene,
As you may recall, my Dodge has the optional 20" wheels...not quite "bling" but tows excellent.
Lots of miles this past year.

Good, I got a question for ya. What series is it? I have a 1500/5.7L (Yea, it's a Hemi ;) ) and was wondering how well it would tow my Chevelle. What motor do you have? If its not the CTD, any problems power-wise towing?

Been meaning to ask, but forgot until you sparked my imagination.

Chris,
It's an '04 Ram Quad Cab Sport 2WD w/Laramie trim...1500 series, 5.7L Hemi, auto, got 22K miles on it now.
Ordered with the factory tow package including 3.91 Sure grip. Tows the Chevelle absolutely awesome, 80 mph on cruise all day long. Probably put 10K miles on it this year with the Chevelle dragging along behind it (open trailer). Averages 10-11 mpg towing.
Thanks for asking...sorry Gene for sidetracking... :eek:

Gene, from my experience it is not so much how the "wheel" will effect towing capacity, but more so the "tire".

For example, our new Silverado SS has a larger engine with about 80 more HP than our previous 5.3 litre 4 X 4, and also a 4.10 rear as opposed to the 3.73. I would have thought the towing capacity would have been much greater, but it is rated exactly the same. The reason is the low profile, performance 20" tires on the SS. Lots more power with this truck, but it does not relate to increased towing capacity due to the tires. I suppose the wheels could also have something to do with it.

Hope this helps.

I put the 20" rims that were on my '02 4x2 Silverado on my '05 Avalanche. The rims are rated at 2400# and I think the tires are rated about 2600 (285-50/20). Considering the truck weighs 5500 and an ideal class III towing limit is 5000# [500# tongue wt], that still only get me into the 6000# gross range. so don't think it is much of an issue. With the 5.3L and the 4.10 gears, my truck is rated for a 10,000# (might even be 11,000#) trailer. THat would still only place 1000# on the tongue, but just about any truck would need a weight distributing hitch for stability at that point. If you go with 18" rims, you are most likely into a 285-60/18 to get to the 31.5" ht range of a stock tire. In my case, I ended up smaller diameter from the stock 31.6" to 31.2" (no big deal , 1-1/2% effective increase in gear ratio).

PS - make sure to check the wheels, the rating is cast into the back of all alum wheels. I had first looked at some nice looking, but less costly rims, ended up, they were only rated to 1750#, glad I caught that. Wheels I have now are KO, much better quality.

Joe, that helps a bunch since i'll be looking to cheaply "bling" a Tahoe I got for a song. Without checking ratings, I would have likely bought a cheap, yet unuseable set of rims.

( Its a cherry 95 Tahoe, the mill seems a little anemic, but its absolutely mint and the price was too good to be true.)

Thnx all!

Hey Lord is a capital L, not that I'm judgin' , just a-tellin.

Well the high class boys around here ( mostly ball players ) dont spin' em anymore, but I do ( did , it's winter) see quite a few. Not my style. Simply want dedicated tires for winter use ( hunting/snow mobiling), so I'll put a good traction tire on the stock rims. But something a but different for the summer.

With all the layoffs and potential layoffs around here, unfortunately you can find good bargains on stuff. Hoping to find some well shod 20" rims for $500-600.
